I am currently attempting to replace the Troll playable race with the Vrykul playable race.  I tried to enable the Vrykul race following a tutorial, and I went through it several times, making sure I was doing everything correctly, but I kept getting an "ERROR accessing memory at {some address} the memory could not be "read""  message.  So, I tried to just replace the models opf the troll race with the vrykul ones, by changing the entries in CharSections, switching ID's 8 and 16 (troll and vrykul).  However, I came across two problems, firstly that the models are too large, and editing CreatureDisplayInfo didnt help, and secondly that the faces are completely untextured, they are just black.  If someone could point me in the right direction or help with these errors, that would be a huge help, thanks!

Update: I threw CharSections serverside, now I can see my face, but theres none of the beards and hairstyles, just skin color and hair color moddable (not entirely sure on this because I cannot see face during customize, but I tested a few times with randomize)

Update2: Ok, so I changed some other DBCs, and now I have hair and facial hair, but I still cannot see on character creation screen because the model is too big, and there are no female models, which works out really strange (and its kinda funny to mess with)

Update3:  I have decided to actually implement the Vrykul race instad of modifying the Troll race, because it screwed with npc models.  I am basically ignoring changing LUA and XML files currently, trying to just get the race to work by changing race in the database, instead of the character creation screen.  However, my core keeps saying my player has an incorrect race/class pair even though the DBC says it's fine, the race is enabled in the core, and I even have levels associated with the race.  I'm not sure where to go from here

Update4:  With much work, a download from the internet for a dbc, and a russian forum for an error fix, I have solved my problem.  I cannot delete this post however :/
